Mission Highlights:

The first payload carried on SA-2 and SA-3 was called Project
Highwater, authorized by NASA's Office of Space Sciences. The
inert S-IV and S-V stages for these launches carried 109,000
liters (30,000 gallons) of ballast water for release in the upper
atmosphere. This was used to study the effects on radio
transmission and changes in local weather conditions. At an
altitude of 150km, explosive devices ruptured the S-IV and S-V
tanks and in just five seconds, ground observers saw the formation
of a hugh ice cloud estimated to be several kilometers in diameter.
